Arteriovenous anastomoses
Modern endovascular methods of treatment of arteriovenous anastomoses:
- Using spirals or balloons
- With the help of liquid embolizing substances
Arteriovenous fistula is an abnormal connection between the artery and the vein. Native pathology is often combined with the presence of several communication vessels. In this regard, the complete elimination of pathology is often impossible. Treatment can consist in embolizing the area of pathology by the method of stationary occlusion or in its surgical removal.
Examples of treatment of arteriovenous anastomoses
AV shunt of anterior cerebral artery
The operation was performed by the method of stationary balloon occlusion of the place of formation of pathological shunting
Before surgery
After surgery
Angiogram of AVM mixed type of spinal cord
Before exclusion from the circulation
After the operation, the AVM is turned off from the circulation
Arteriovenous anastomoses mixed type
CT scan before surgery
The AV shunt of the posterior cerebral artery is disconnected using separable GDC spirals

After surgery
From the pool of the internal carotid artery AVM is disconnected from the blood stream using a liquid embolizing agent
